Historian Eunan O'Halpin investigates the hidden violence inside Ireland's War of Independence and Civil War, the disappearances of men accused of spying for the British and quietly executed by republican forces. Away from the heroic version of the story, O'Halpin traces individual cases where suspicion, rumor, or personal grudge got a man shot and buried without record. The film follows exclusive access to an excavation at one of these burial sites, filming archaeologists and forensic specialists as they work to recover remains and identify a victim nearly a century after the killing. Archival photographs, contemporary documents, and interviews with historians fill in the political pressure that made secret executions possible, and family testimony gives the missing men names instead of statistics. Tile Films built the documentary around that dig, using it as the through-line for a broader account of how a war fought partly in the shadows left bodies that were never properly buried or acknowledged, and how present-day forensic work is finally answering what happened to them.
